KANSAS CITY, MO. – It makes plenty of sense, this platoon system that Rocco Baldelli began using 10 days ago. Max Kepler and Miguel Sano are each suffering through excruciating seasons, both are hitting below .200, and Kepler is lefthanded while Sano bats from the right side.
So limiting Kepler to days the Twins are facing right-handed starters, and Sano to the lefties, allows Baldelli to keep promising rookie Alex Kirilloff, who can credibly play right field or first base, in the lineup and theoretically allows the veterans to work out of their slumps by usually having the platoon advantage.
Only one problem: Sano has been worse against lefthanders than right.
"I can't tell you it's something that was expected. I mean, Miguel's had a lot of success in his career," Baldelli said. "That has been difficult because when we're facing these lefthanders — and we do face a good number of lefthanders — being able to look to Miguel for that production is something we've relied on in a big way."
As a team, the Twins have displayed a lot of power against lefthanded pitching; their .424 slugging percentage ranks second in the AL behind Houston.
But Sano has rarely been a part of it. Only three of his 14 home runs are against lefthanders, and the drop-off in extra-base hits is alarming: He owns an above-average .520 slugging percentage against righthanders, but a miserable .280 against lefties. His batting average against lefthanders is just .171 (compared with .203 vs. righthanders), and his OPS is .533 (vs. .808).
"Some of these lefthanders are changeup heavy," Baldelli said. "It really comes down to being able to make adjustments, knowing who's on the mound and what they're going to do to you."
Even more worrisome: This was a problem for Sano in 2020, too. He batted only .159 with a .341 slugging percentage and .213 on-base percentage while holding the platoon advantage last year. What's strange is that Sano devoured lefties in 2019, posting a 1.007 OPS.
