Robinson Chirinos - Astros (C), Age: 35

Chirinos always showed pop in his bat (35 home runs in 2017-18), but he also struck out a lot with a low average. While his .240 average this season isn't spectacular, he is striking out less, has a .375 on-base percentage, is tied for third among AL catchers with 11 homers, and tied for second with 11 doubles.
