PRINCETON, N.J. — Leading the Columbia softball team to its second ever 4-0 league start, rookies Madison Canby and Sommer Grzybek were honored as Ivy League Co-Rookies of the Week on Monday. Canby was also selected as the Ancient Eight’s Pitcher of the Week.

Columbia (11-13, 4-0 Ivy) walked off three times over the weekend, doing so twice in Saturday’s sweep against Dartmouth and one final time in Sunday’s sweep against Harvard. The Lions came back from three runs down in the sixth inning of both victories against the Big Green, walking off on a Grzybek single in game one and a ninth-inning Grzybek home run in game two. Sunday, they scored four runs in the bottom of the seventh to erase a 5-2 deficit and walk off in game two against the Crimson.

Canby earned all four wins in the circle, dominating to the tune of a 0.94 ERA through 22 1-3 innings pitched. The right-hander earned the complete-game victory in Saturday’s league opener against Dartmouth and tossed her second complete game of the weekend in Sunday’s game-one victory over Harvard. The rookie took a three-hit shutout into the seventh against the Crimson and worked a combined 8 1-3 scoreless innings of relief in her two other appearances. The Pembroke Pines, Florida, native boasted a 0.99 WHIP and limited opponents to .203 at the plate, helping the Lions to their first ever combined season sweep of Harvard and Dartmouth.

Canby’s weekend performance dropped her season ERA from 5.09 to 3.87. She leads the Ivy League in victories with a 7-4 record and has thrown the second-most innings of any pitcher in the Ancient Eight (76.0). This marks her second straight Rookie of the Week selection and first as Pitcher of the Week.

Grzybek delivered in huge moments offensively, hitting .333 on the weekend and slugging .917 with two home runs, three runs and three RBIs. The center fielder went 3 for 8 on Saturday against Dartmouth, including a home run in the sixth inning of game one, followed by a walk-off single in the seventh. She went 1 for 4 in the back end, but made the most of her lone hit by launching a ninth-inning, walk-off blast to left-center.

Grzybek is hitting .315 and slugging .616 on the campaign. She shares the Ivy League lead in home runs (5) and is tied for third in RBIs (15) with junior teammate Madison Gott. Monday marked the second time Grzybek  earned Ivy League recognition, also being named Rookie and Player of the Week on March 20.

Columbia returns to action on Wednesday with a non-conference doubleheader at Fairfield. First pitch is slated for 2 p.m.
