Souza tried to rob a home run Friday night but ran full-speed into the right field wall, his shoulder colliding with the wall. Souza fell to the ground in a heap. He came out of the game a half-inning later and pinch-ran for Jayson Werth in the 11th inning last night, but will now be out at least the next 15 days. Taylor hit a combined .315 with 20 doubles, 22 home runs, 63 RBI and 35 stolen bases in 102 games this season for Double-A Harrisburg (98 games) and Triple-A Syracuse (four). He possesses elite defensive ability, according to scouts. Back in spring training, Matt Williams said Taylor's defense rated as an 80 on the 20-80 scouting scale. He has struck out 132 times in 397 at-bats this season, but his offensive ability has really progressed in the last year. Now, the 23-year-old will get his first crack at the big leagues.
