Heyward went 1-for-1 with a three-run homer in Tuesday's win over the Mariners.
Heyward was brought in as a pinch hitter in the eighth to face Andres Munoz and capitalized with a three-run laser over the short wall in right field. Heyward has been highly successful as a pinch hitter this season, going 4-for-8 with a pair of home runs. Tuesday's long ball was his first since July 21 and this marked his first multi-RBI performance since then as well. The 34-year-old is slashing .208/.289/.393 with six homers, 28 RBI, 25 runs, four steals and a 17:36 BB:K in 197 plate appearances this year.
