NEW YORK - After a 4-1 win in the Ivy League opener against No. 20 Cornell last weekend, the No. 22 ranked Columbia men's tennis team welcomes Penn on Friday before heading to Princeton on Sunday.

The Lions (12-3) host Penn (13-6) Friday at 1 p.m. in the Dick Savitt Tennis Center, before traveling to Princeton (10-9) on Sunday at the same time.

With the decisive 4-1 win over Cornell last weekend for the second time this spring, Columbia is now tied in the Ancient Eight standings with Yale (15-4, 1-0) and Harvard (13-8, 1-0).

A doubles point victory and three singles wins was all it took last time out for Columbia to best the No. 20 team in the nation for the second time this season. Shawn Hadavi and Jackie Tang, who are featured at No. 87 in the latest ITA rankings, were the first to finish their doubles match in 6-3 fashion, which was the same score that Michal Rolski and Christopher Grant were triumphant in to clinch the point.

In singles play, Hadavi was dominant in the top spot. The senior and No. 97 ranked player cruised past David Volfson, 6-1, 6-2, putting the Lions up 2-0 and improving his unbeaten streak to nine matches. Quickly thereafter, the No. 2 singles point was claimed by No. 67 Victor Pham, who upended Colin Sinclair, 7-5, 6-2.

After Cornell stole the No. 5 singles match, sophomore Timothy Wang ended things at the Dick Savitt Tennis Center with a 7-5, 6-0 win at No. 6.

Along with Hadavi and Pham, Jackie Tang was also featured in this past week's singles rankings at No. 125, dropping from No. 90. On the doubles side, Victor Pham and Richard Pham held firm at No. 28, sliding a few spots from their previous No. 19 ranking.

As Columbia has not dropped an Ivy League match since 2013, the records against this weekend's opponents have favored the Lions as of late. Columbia has 11 consecutive wins against Penn, who has not knocked off the Lions since 2006, and has also defeated Princeton seven straight times, with the last loss coming in 2011.
