It was actually 10 RBIs. I listened to both games and he caught most of both games as well. He had 13 RBIs total today, and 21 in the four games.
His totals for the four games are 15-22, 2 2Bs, 2 3Bs, 6 HRs, BB, HBP, SB, 21 RBIs.
It is a hitter's park and there was a strong wind going out to center, but still. His HRs today were to right, left, right center, and center.
EDIT: Sorry, he had six home runs in the four games. He has 29 in 62 games this year.
Edit 2: If I did the numbers right, he had a .682 BA, .708 OBP, and an 1.819 Slugging %. A 2.527 OPS isn't too shabby:)
