Maples signed with the Phillies as a non-roster invitee Tuesday, Matt Gelb of The Athletic reports.
The 29-year-old is great at missing bats, posting a 30.6 percent strikeout rate in 54.2 career major-league innings. Unfortunately, it seems as though neither he nor his opponents know where his pitches will end up, as he's also walked batters at a 19.4 percent clip, leading to a poor 5.10 ERA. If he ever sorts out his control issues, he could be a real weapon out of the bullpen, but it's highly unlikely that he'll suddenly correct such a significant issue in his 11th professional season.
