It’s tough to get much attention when AL ERA leader Felix Hernandez is your teammate, but Hisashi Iwakuma is quietly emerging as a formidable sidekick at the top of the Mariners’ rotation.
Iwakuma gave up two runs over seven innings last night in a 6-3 win over the Athletics. The 32-year-old struck out nine and walked none while retiring 16 batters in a row at one point. Brooks Baseball notes that he had 12 swings and misses, including five on his splitter, which has emerged as a legitimate weapon during his brief time in the majors.
Just to give you a sense of how good Iwakuma has been this season, his ERA actually went up from 1.61 to 1.74 with last night’s start. Still, he hasn’t allowed more than three runs in any of his eight starts this season and owns a stingy 51/8 K/BB ratio over 51 2/3 innings. His 0.74 WHIP is the best in the American League. And to think, he has pitched most of the season with a blister on the middle finger of his throwing hand.
Iwakuma’s dominance actually dates back to last season, as he has a 2.33 ERA in 24 starts since moving to the rotation last July. Only Justin Verlander, Clayton Kershaw, Matt Harvey, and Kris Medlen have a lower ERA in the same timespan. It’s unlikely that he’ll be able to maintain his .198 batting average on balls in play (BABIP) and 84.4 percent strand rate, so some regression should be expected, but the Mariners’ decision to keep him around on a two-year, $14 million deal looks pretty smart right now.
The Giants have acquired All-Star infielder Eduardo Nunez from the Twins in exchange for minor league pitcher Adalberto Mejia, the club announced on Thursday night.
Nunez, 29, went 0-for-4 in Thursday night’s game against the Orioles. He’s hitting .296/.325/.439 with 12 home runs, 47 RBI, 49 runs scored, and a league-best 26 stolen bases in 391 plate appearances this season. Nunez has played mostly at shortstop this season, but has also logged significant time at third base and a handful of games at second base, so he’ll give the Giants some versatility.
Nunez will likely play a lot of third base for the Giants as Matt Duffy is still sidelined with a strained left Achilles. He’s earning $1.475 million this season and will enter his third and final year of arbitration eligibility heading into 2017.
Mejia, 23, was considered the Giants’ seventh-best prospect by MLB Pipeline. He earned a promotion to Triple-A Sacramento last month after posting a 1.94 ERA with Double-A Richmond. In seven starts with Sacramento, he has a 4.20 ERA with a 43/11 K/BB ratio in 40 2/3 innings.
With a roster spot open, the Twins called up infield prospect Jorge Polanco from Triple-A Rochester, per MLB.com’s Rhett Bollinger.
Bob Nightengale of USA TODAY reports that the Mariners have received “strong” trade interest for starter Taijuan Walker. The right-hander is currently on the mend from tendinitis in his right foot. He’ll throw a bullpen on Friday at Wrigley Field with scouts in attendance.
Walker, 23, has a 3.66 ERA with an 80/18 K/BB ratio in 86 innings this season. It’s his first bit of sustained success at the major league level. What’s arguably just as intriguing is the fact that Walker will be under team control through 2020.
The Mariners have been hovering around .500 for the last month and entered Thursday six games behind the first-place Rangers in the AL West and 4.5 games out of the second AL Wild Card slot, behind three other teams as well as the two Wild Card leaders. It’s enough uncertainty which could push the Mariners to sell.
