Ian Stewart had a monster day in the first game of Saturday's doubleheader at Triple-A Iowa, going 3-for-4 with three homers and eight RBI. Stewart got the party started with a three-run blast to right-center in the second inning. He then launched a two-run homer to virtually the same spot in the fourth. After striking out in the sixth, he broke a 5-5 tie with a three-run bomb the opposite way in the eighth. While the huge day is a nice accomplishment, he was hitting just .146/.259/.250 with one homer and 10 RBI through 35 games heading into play on Saturday and isn't close to returning to the Cubs.
