Some big names made their MLB debuts with 2022 MLB draft pick Ben Joyce joining the Los Angeles Angels bullpen, along with Sam Bachman. Meanwhile up the freeway Bobby Miller earned a win in his Los Angeles Dodgers debut and currently has a 2-0 record with a 1.64 ERA, but that is not good enough for the best debut or the best month. Even further up the California freeway system, Patrick Bailey is hitting over .300 with a couple home runs and a dozen RBI, but he didn’t have the best debut month for the San Francisco Giants in May. For both the pitcher and batter, the player with the best debut was also the player with the best first month. 

Best Hitting Debut & Month:

Casey Schmitt, 3B, San Francisco Giants – Schmitt went 2-4 with a solo home run in his debut, making him the only player to homer in his debut this month. He has gone on to hit another home run, is hitting .325, driven in 16 and crossed the plate a dozen times. Schmitt has been arguably the best player on the Giants over the past month. 

Best Pitching Debut & Month:

Bryce Miller, RHP, Seattle Mariners – Miler didn’t get the win on his debut, but he went six innings while allowing just a single run with two hits. He wound up striking out 31 batters in his 36 innings on the month, with an ERA of an even 3.00 and a 3-2 record.
