Cordero made a splash upon arrival in April. He recorded exit velocities of 110 and 115 mph in his first big-league game of the season and went on to collect six homers in his first 15 games, including an unbelievable 489-foot shot, which was one of the longest home runs hit in all of the majors. His numbers eventually started to slide and the Padres picked up on a mechanical change he was making to compensate for a bothersome bone spur in his left elbow. Eventually, Cordero had surgery to remove the spur. When healthy, Cordero flashed incredible athleticism and quick-twitch ability, but he's certainly not without his flaws. He hasn't had a strikeout rate below 25 percent above A-ball, and despite his athleticism his defense graded out poorly last year as he routinely misread balls off the bat. Cordero has power/speed upside, but he will need to prove his health and fight to carve out playing time in spring training.

As an endgame play in deeper leagues, Cordero has a chance to pay dividends in 2018. He struck out 44.4 percent of the time in 30 games in the majors last season, but that doesn't mean he is doomed (Aaron Judge did the same thing in 2016). Cordero, who won't turn 24 until September, has plus raw power and enough speed to steal double-digit bases over a full season. He also rates as a quality defender at all three outfield spots. Cordero rarely makes soft contact (12.2 percent last season), and while his swing-and-miss issues will likely prevent him from ever hitting for a high average, the raw tools are here for him to be a four-category producer. Manuel Margot is assured of a spot in the outfield long term, but the other two spots are not nailed down. Hunter Renfroe and Jose Pirela may be the only two players standing between Cordero and everyday work in an outfield corner. He impressed in the Dominican Winter League this offseason, and will look to be more successful against MLB pitching when his name is called.

Cordero performed well at High-A Lake Elsinore and then Double-A San Antonio in 2016, which led the Padres to add him to their 40-man roster following the season for Rule 5 protection. In his 322 plate appearances in High-A, Cordero slashed .286/.339/.444. His numbers only improved upon arrival to San Antonio and his overall performance earned Cordero a brief callup to Triple-A El Paso at the end of the season. Cordero is a solid runner, as evidenced by his 23 total stolen bases in 2016, but his disappointing walk rates have kept him from being more of a threat on the bases. While Cordero has displayed some impressive tools, his slow development now at age 22 likely limits his ceiling to that of a fourth outfielder.
