If the coupon for event number 12 is still in your H.A.A. ticket book tonight, you'll have missed the best wrestling match of the season. Harvard meets Princeton at 2 p.m. in the Blockhouse.

Princeton tied Navy two weeks ago and this attests to its strength more than anything else. The Middies, winners of 50 straight matches, undefeated and untied for seven years, were hard-pressed to gain a 14-14 deadlock.

Besides Navy, the mighty men from New Jersey have rolled over Rutgers, Gettysburg, and Yale (20-6), tied Penn, and lost to Penn State, one of the cast's wrestling powers. Under Coach Jim Reed, the Tigers have shown consistent improvement in every department.

Coach Butch Jordan's band, trying for its sixth win in seven starts, has a good chance of getting it, but the outcome will depend on a few key matches and the Crimson must record plus in at least two of them. Once again the best two bouts should be the 128-pound and heavyweight tussles.

Dave Smith, back at 128 for today's match, meets Dave Poor. If Smith gets the jump on his opponent early in the match he should win. Besides being Jordon's most capable wrestler he is a first class showman too.

The visitors' strength lies, mainly in the lightweight brackets. Dave McAlpin, for instance, who faces Joe Kozol at 121, has pinned in his last two outings.

155-Pound Slot Doubtful

Bob Abboud moves back to 136 today and Tom Connors, who has already wrestled at 175 and 165, may replace Rod Skinner at 155. If he does, he will face Captain Russ Randall (five wins, one defeat). Both Connors and Skinner will weigh in this morning.

Buddy King stays at 145 and Stan Thompson goes back to 165. He opposes Dale Longacre, who came up from the jayvees in time to lose in the Yale match. Captain Bob Claflin's 175-pound opponent is mediocre and also lost against Yale.

Howie Houston gets his first real test today against Reddy Finney. Finney decisioned the Navy heavyweight and the 300-pound Penn heavyweight, but Houston should win in an interesting match. It's Howie's last home appearance and it's worth the price of admission just to watch him.
