Pirates pitcher Mitch Keller is being terribly overlooked in fantasy baseball

There are a lot of things in the world that confuse, and often infuriate, Roto Rage. Here’s a quick top five:

After allowing four earned runs and walking four in his first start, Keller has not allowed more than three earned runs in any of his six starts since. He is 3-1 with a 2.75 ERA, 40-9 strikeout-walk rate, .225 opponents’ average and a 10 percent swinging-strike rate in that span. He has also struck out at least seven batters in five of his seven starts, and had just as many quality starts.

Among qualified pitchers, Keller ranks 14th in strikeouts per nine innings (10.62, sixth-best in the NL) and 30th in ERA (3.32, 22nd in the NL). His .228 opponents’ average ranked 14th in the National League and his 1.20 WHIP was the 18th-best mark.

Keller’s swinging-strike rate (10 percent) was in the top 40 (he was No. 40) entering Friday, and he has had some impressive swing-and-miss performances, including a 13 percent rate over his past two outings, against the Dodgers and Rays. He struck out 18 and walked two while allowing three earned runs and a .222 opponents’ average in those starts.

Keller’s 7.6 percent walk rate was not only a career low, but it was among the 20 best in the NL and top 50 in the majors. He also is limiting hard contact, with his hard-hit rate ranking in the top 6 percent of the league.

The 27-year-old has done all this by relying more on his secondary pitches. Though opponents are hitting .174 with a 27.8 percent whiff rate and 13.8 percent swinging-strike rate against his fastball, batters are also struggling against his cutter (the newest pitch in his arsenal). Opponents have hit .179 with a 27.5 percent whiff rate and 13.3 percent swinging-strike rate against the cutter. They also are hitting .231 versus his curve and .214, with a 27.7 percent whiff rate, against his sweeper.

The fact Keller’s expected ERA (3.52), FIP (3.31) and xFIP (3.58) are all within 20 points of his actual ERA is a great sign for where he is headed this year (as is the fact the Pirates owned the second-best record in the NL entering the weekend). Fantasy managers should be taking notice of that.

Other pitchers who deserve to be rostered in more leagues:

Eduardo Rodriguez (64 percent rostered) has allowed two earned runs over his past five starts for Detroit while going 3-0 with a 0.52 ERA. During this impressive stretch, he has had a 33-4 strikeout-walk rate, .157 opponents’ average and 11 percent swinging-strike rate. From April through Thursday, the lefty had the best ERA in the majors, as well as the seventh-lowest walk rate (1.04 per nine) and the fourth-lowest opponents average.

Roto Rage is once again going to go to bat for Tampa Bay’s Zach Eflin, who is rostered in just 36.5 percent of ESPN leagues, because the righty is more than just a streaming option. In his first three starts off the injured list, he is 2-0 with a 1.59 ERA, 19-2 strikeout-walk rate, .197 opponents’ average and 12 percent swinging-strike rate. That includes striking out 10 over seven shutout innings Thursday against Pittsburgh.

Two guys to keep an eye on, who are rostered in fewer than 15 percent of ESPN leagues include Seattle’s Bryce Miller (12 percent), who struck out 10 in his big league debut (it was against Oakland, so see how he does against actual competition), and Washington’s Josiah Gray (12.9 percent), who had a 1.57 ERA and .219 opponents’ average in his past five starts before taking the mound Friday and has a favorable schedule over his next five or so starts.
