Two weeks ago, I wrote about the underachieving Twins offense. At the time, Minnesota was scoring one run fewer per game this year than last year, and I concluded home runs were the culprit.

Simply put, the Twins weren't hitting as many home runs as they did last season — and of the 48 homers they hit through the first 50 games, 32 were solo, 14 were two-run shots, plus one each of the three-run and grand slam varieties.

Since then, the Twins have played 13 games, scoring 69 runs — an average of 5.3 per game. They've hit a whopping 20 home runs in that span, and 10 of them came with runners on (five two-run shots, four three-run shots and Tuesday night's grand slam for Ehire Adrianza that fueled Minnesota's 6-4 win over the Tigers).

That's about 1.4 runs more per game than they were getting via homers through the first 50 games — accounting for a surge to 5.3 runs per game in the past 13.
