Winn went 1-for-4 with a two-run homer in Sunday's 6-2 loss to the Cubs.
Winn opened up the scoring with a two-run blast off Justin Steele in the third, but the Cardinals would be shut out the rest of the way from there. Wynn now has four homers over his last 10 games and is up to nine total for the season. Seven of his nine homers this season have come against left-handed pitching. The 22-year-old is slashing .279/.325/.414 with 31 extra-base hits, 41 RBI, 50 runs, nine steals and a 29:75 BB:K in 426 plate appearances.
