Going to be 25 next season, Register went 1-3 with 37 saves and a 4.03 ERA last season in 61 games.

The Mets have to hold him on the Major League roster all season or send him back to Colorado.

Back when he was drafted out of Auburn in 2004, Baseball America had this to say:

He’s a strike-thrower; he has good command. He’s got an average fastball with above-average life that sinks and bores. He can be up to 93 (mph), but he doesn’t get a good hip turn or get balanced over the rubber and in turn, he’s never quite consistent with his release point and sometimes loses the life on his fastball.

He’s got an average to plus slider with a short break and some tilt. At times, it’s an out pitch. His changeup is not an average pitch. He’s got to use it more to get better, but he doesn’t have to at the college level.

UPDATE: In the AAA Phase, the Mets selected Garry Bakker from the White Sox, who went 2-7 with a 3.67 ERA in 31 games (11 starts) for Winston-Salem (A) of the Carolina League last season.
