Not too many minor leaguers feel bittersweet when they get a promotion, but for Double-A Arkansas righthander Tyler Chatwood, leaving high Class A Rancho Cucamonga also meant leaving the place where he grew up. But now, after a rough introduction, Chatwood seems to feel just as comfortable in the Texas League as he did in California.

Yesterday Chatwood held Springfield to one run on five hits over six innings. After a rough start with the Travelers, Chatwood has allowed just five earned runs in his last 35 innings over his last five starts, using a heavy fastball in the in the low to mid-90s that hitters pound into the ground as well as a plus curve. Still just 20, Chatwood's changeup is a third pitch, but he's even started showing some feel it as well on the occasions he does throw the pitch.

Louis Coleman, rhp, Royals (Triple-A Omaha): Add another player to the impressive collection of young Royals pitchers to watch. Coleman, a 2009 fifth-round pick, has been fantastic for Omaha since being promoted at the beginning of July. A former starter for LSU, Colemanhas moved quickly as reliever, with all but one of his 32 professional appearances coming out of the bullpen. The angle he creates against righthanded hitters makes him tough to pick up, and in 20 1/3 innings with Omaha, Coleman has a 2.66 ERA with 24 strikeouts and four walks.

Trayvon Robinson, cf, Dodgers (Double-A Chattanooga): Robinson reached triple-digit strikeouts in each of his last two seasons with high Class A Inland Empire, and he is knocking on the door again with 99 this season. After a hit and two more walks last night, it might not matter, as Robinson's OBP is pushing .400 with a .308/.399/.457 line with nine homers and 31 steals in 42 attempts.

Cito Culver, ss, Yankees (Rookie-level Gulf Coast League): Culver wasn't a consensus first-round talent when the Yankees took him there in June, and a .235/.319/.309 start with six errors in his first 23 games didn't help. Yet the 17-year-old has been better lately with an eight-game hitting streak, hitting both of his home runs on the year in that stretch to bring him up to .288/.338/.383 through 34 games.

Wilson Ramos, c, Nationals (Triple-A Syracuse): The Nationals might have gotten a steal in Ramos in exchange for sending Matt Capps to the Twins. Ramos, 22, was having a difficult year at the plate with the Twins, but since moving to his new International League club, Ramos has yet to strike out in 20 plate appearances and is hitting .350/.350/.650 for the Chiefs.
