Some players take unusual paths to the big leagues. And then there is the journey of Jonathan Pintaro. Undrafted from a Division II college in Georgia, he spent two seasons in the MLB Draft League for overlooked long shots. Then two years pitching for the Glacier Range Riders of the independent Pioneer League — where he compiled a 6.60 ERA. So when Pintaro walked into the New York Mets’ clubhouse Wednesday, about 2,400 miles from 2,291-seat Glacier Bank Park in Kalispell, Montana, needless to say it was an improbable arrival. Pintaro received a surprise promotion from the minors when the struggling Mets shuffled bullpen arms again before their 7-3 victory against Atlanta.
