It happens every year. Players have breakout seasons or make an instant impact. They can be young players who make the game look easy, or players with some experience that suddenly figure things out.
This season, we are trying to figure out how to pronouce Jean Segura's name (it's Jean as in blue jeans). And we are wondering if Daniel Nava can continue to come through with clutch hits. They are among this list of ten players who have been some of the biggest surprises this season.
1. Josh Donaldson, 3B, Athletics
He was sent down twice last season, once after hitting .094 in April and again after batting .182 in May and June. He returned in August and stuck around on a team that reached the playoffs. This season, his plate discipline is vastly different, and he entered the weekend batting .310 with nine homers and 42 RBI.
2. Patrick Corbin, RHP, Diamondbacks: Part of the trade for Dan Haren in 2010, Corbin (9-0, 2.28) is making the Angels pay for dealing him. He throws four pitches for strikes and uses his slider to finish off hitters.
3. Jason Grilli, RHP, Pirates
He had five career saves heading into the season. Now Grilli is living large with a 0.94 ERA and 23 saves. And his 47 strikeouts would lead the Twins pitching staff.
4. Shelby Miller, RHP, Cardinals: Oh, to be 22 years old and have a 97 miles-per-hour fastball. Miller (7-4, 2.21) has stepped up on a Cardinals staff that has been hit with injuries. On May 10, he gave up a leadoff hit, then retired 27 straight batters.
