Welcome back to Top of the Order, where every Tuesday and Friday I’ll be starting your baseball day with some news, notes, and thoughts about the game we love.
The Mariners are in the driver’s seat in the AL West, with a 5.5-game lead over the Astros, and an 80% chance of making it back to the playoffs after narrowly falling short last season. And considering that they just played their 81st game last night, a tough 4-3 loss to the Rays in which they led 3-1 entering the eighth, now seems like a good time to evaluate what moves president of baseball operations — and notorious trader — Jerry Dipoto should make between now and the July 30 trade deadline.
Seattle’s success has been driven by its pitching, especially its starting five. Only the Phillies, Yankees, and Orioles have gotten lower ERAs out of their rotation, and after play concluded on Sunday, Mariners starters had pitched 23 more innings than Yankees starters in the same number of games. The M’s arguably have three aces in Luis Castillo, George Kirby, and Logan Gilbert; their fourth and fifth starters, Bryce Miller and Bryan Woo, aren’t too shabby either. Woo’s innings will probably have to be managed carefully down the stretch after he began the season on the IL due to forearm issues, which also have caused him to leave a few starts early. He was removed in the fourth inning of Monday’s game with right hamstring tightness, though it’s unclear yet how much time, if any, he will miss. Either way, the Mariners can withstand a limited or absent Woo because of how many innings the front three are able to cover.
Their relievers are generally doing their jobs as well, with the group ranking 13th in bullpen ERA entering Monday, and co-closers Andrés Muñoz and Ryne Stanek have done a solid job finishing off games. The depth of the bullpen was supposed to be a strength entering the season, but with Matt Brash and Jackson Kowar out for the season and Gregory Santos yet to throw a pitch this year, the Mariners are a little thin in the middle innings. Still, Santos is expected to start a rehab assignment soon, and the lower-level bullpen issues ought to be easy to address with minor moves between now and the trade deadline.
Seattle’s tepid offense, on the other hand, won’t be such a simple fix. Its 97 wRC+ ranked 17th entering this week, and the guys who were supposed to be carrying the lineup (Julio Rodríguez, J.P. Crawford, Cal Raleigh, and offseason additions Mitch Garver and Jorge Polanco) have all been below average over the first half of the season. Strong contributions from Luke Raley, Dominic Canzone, Dylan Moore, and Josh Rojas — along with a resurgence from Ty France — have kept the offense from being even more disappointing, but this lineup still isn’t good enough for the Mariners to make a deep playoff run. Raleigh is the only Mariners player with at least 10 home runs at the halfway point of the season; he’s pacing for 26 homers, four fewer than last year. Rodríguez’s power is also down this season. He’s launched just seven home runs after putting up his first 30-homer campaign last year. It’s worth noting that Rodríguez struggled through the first half of 2023 as well. At this point last year, he had 13 home runs and a 104 wRC+ before exploding for 19 dingers and a 145 wRC+ the rest of the way, so the Mariners should be confident that the 23-year-old phenom will turn things around. However, even with Julio at his best, Seattle needs more offense.
There will, as always, be rental bats available. Guys like Tommy Pham or Josh Bell (especially if he’s on one of his yearly hot streaks) would certainly help the Mariners add depth and lengthen their lineup, but they need a game-changer, someone to make pitchers sweat, and nobody like that exists on the rental market unless the Mets are willing to trade Pete Alonso. So Dipoto might have to go big, even if he has to give up Miller or Woo or a top prospect like Harry Ford or Cole Young in such a move. Here are some of the players the Mariners should target in a trade:
**Risky Rooker**
Brent Rooker is good at one thing: hitting the crap out of the ball. He’s best suited as the DH instead of playing the outfield. He also walks at a solid clip and strikes out a ton. But when he does connect, few hitters in the league make more optimal contact. Rooker is above the 90th percentile for xSLG, barrel rate, hard-hit rate, and sweet-spot percentage (he’s better than Luis Arraez there!), helping him pop 43 homers since the start of 2023 after being claimed off waivers by the A’s in the 2022-23 offseason. Most importantly, his power plays anywhere: He’s got 13 home runs this year, and he’d actually have a couple more if all of his batted balls were in Seattle, per Statcast. The thing about Rooker is he’s streaky. Last year, he had a bonkers 232 wRC+ in March/April and then posted monthly marks, in order, of 77, 74, 144, 94, and 159 the rest of the way. This season has been a similar story. He had a 122 wRC+ over the first month and a 185 mark in May, but he’s down to 84 in June. Still, even a streaky Rooker would benefit the Mariners, especially because he’s under club control through the 2027 season.
**Trading With A Familiar Team**
The Rays are never ones to shy away from trading off their big league roster, even when they’re in contention for a playoff spot. And they’re certainly never ones to shy away from trading with the Mariners, with last offseason’s José Caballero-for-Luke Raley deal the most recent example in a long line of swaps between the two teams. While the Mariners were interested in Rays third baseman Isaac Paredes last offseason, I’d argue that acquiring him wouldn’t work out well. Paredes has made a name for himself with his signature pull-side power, but that approach wouldn’t be as beneficial if he were playing his home games in Seattle. According to Statcast, only six of Parades’ 11 home runs this season would’ve been gone at T-Mobile Park, which has extremely hitter-unfriendly park factors; this year, the environment is reducing batted ball distance by an average of six feet, not good for a hitter like Paredes who relies on optimal horizontal spray angle. Randy Arozarena has struggled mightily this season, and Brandon Lowe is too injury-prone to be relied upon as a true lineup-lengthener. But how about Josh Lowe? He’s missed some time this year due to injuries, but he’s mashed when healthy and boasts plus power and speed. Like Rooker, Lowe is controllable; he isn’t set to reach free agency until the after the 2028 season. For this reason, the Rays would ask for a lot in return. But Lowe would be an excellent fit for the Mariners, essentially the lite, left-handed version of our next and final trade possibility.
**The White (Sox) Whale**
Injuries are always going to be at the forefront of any discussion about dynamic White Sox center fielder Luis Robert Jr. Most recently, he missed 55 of Chicago’s first 79 games this season after re-injuring the same hip that limited him to 68 games in 2021. But what he did last year, in his first and only full season, should make teams looking to upgrade their lineup drool at the possibility of acquiring him. Robert has 40-homer power and the speed to swipe 20 bases. He’s also an excellent defensive center fielder with a strong throwing arm, tools that should make him an elite right fielder — where he’d almost certainly slide because Seattle already has Rodríguez in center. Robert is not without his flaws; in addition to his injury history, he strikes out a ton and doesn’t really take walks. But he would clearly be the second-best position player on the Mariners and the game-changing…
