The Phillies promoted their No. 1 prospect, righthander Carlos Carrasco, to Double-A Reading. The 20-year-old Venezuelan got off to a slow start at high Class A Clearwater, with reports that his fastball was sitting in the high 80s in April, but he caught fire in his last six starts, going 3-1, 1.19 over 37 2/3 innings in that span. He threw a complete-game three-hit shutout in his last outing, June 11 against Fort Myers. Carrasco will pitch for the R-Phils tomorrow night against Binghamton.

The Phillies also demoted righty Zach Segovia from Triple-A Ottawa, where he was 1-9, 6.05, to Reading, as he trades places with veteran righty Heath Totten.

Another promotion that came down in the last week is the Mariners’ promotion of righthander Kam Mickolio to Triple-A Tacoma. Mickolio is quite a story, a raw kid from Montana who spent two years in junior college and two more at Utah Valley State, one of the nation’s newer Division I programs. Mickolio topped out at 92-93 mph as a college senior, but most scouts saw him throwing more consistently in the mid-80s. He’s 6-foot-9, though, and at times gets an excellent downward plane that makes him tough on hitters.

The Mariners signed him in the 18th round last year and he had a strong debut, checking in at No. 19 on the Northwest League Top 20 prospects. After a strong spring training, though, he made one of the biggest jumps in the game this year, making his full-season debut at Double-A West Tenn. Then came the bigger surprise–working exclusively as a reliever, Mickolio dealt, posting a 1.82 ERA in 29 2/3 innings, striking out 27 and giving up no home runs. The fast-tracking Mariners have now pushed him to Triple-A Tacoma, where he has given up five runs in four innings over two outings.
