UNDATED (AP) — The Chicago Cubs have never been accused of taking the easy path to a playoff series victory. Game 3 of their National League Division Series was proof of that, as if their 108-year championship drought wasn't a subtle reminder.

Joe Panik prevented the Cubs from completing their first-ever postseason series sweep by lining an RBI double in the bottom of the 13th to give the Giants a 6-5 triumph in San Francisco. The Cubs blew a three-run lead, then tied it with a ninth-inning homer before Brandon Crawford and Panik hit back-to-back doubles to force a Game 4 later today. Panik's hit gives the Giants 10 straight victories when facing elimination.

Things were looking great for the Cubs after pitcher Jake Arrieta (ar-ee-EH'-tuh) opened the scoring with a three-run homer in the top of the second. It came off Madison Bumgarner, who had tossed 24 consecutive scoreless innings in the postseason before serving up the second homer hit by a Cubs hurler in the series. Chicago pitchers have collected six RBIs over the last two games.

Arrieta left after six innings with a 3-2 lead, but the Giants attacked the Cubs bullpen in the eighth as Conor Gillaspie laced a two-run triple off Aroldis Chapman and scored on Crawford's RBI single. The game morphed into a marathon once Kris Bryant smacked a two-run homer off Sergio Romo in the ninth.

Ty Blach worked two innings of relief to get the win. Mike Montgomery was the hard-luck loser, tossing four shutout innings of relief before yielding the doubles in the 13th.

Buster Posey had three hits and an RBI for the Giants, who host Game 4. Matt Moore is slated to start for San Francisco against John Lackey.

The Cleveland Indians have advanced to the American League Championship Series while ending the career of David Ortiz.

The Indians completed a three-game sweep of their division series by getting a two-run homer from Coco Crisp and a two-run single by Tyler Naquin (NAY'-kwihn) in a 4-3 triumph over the Red Sox in Boston. Josh Tomlin pitched into the sixth inning for the Indians, who are in the championship series for the third time in 10 seasons.

The game was scoreless until Naquin drove in a pair against loser Clay Buchholz in the top of the fourth. Crisp added a homer off his former team to put the Indians ahead 4-1 in the sixth.

The Red Sox got within 4-3 on an RBI single by Hanley Ramirez, which also put runners on first and second with two out in the eighth. Cody Allen worked out of the jam by getting Xander Bogaerts (ZAN'-dur BOH'-gahrts) to line to second before tossing a scoreless ninth to notch the save.

Tomlin got the victory by limiting the Bosox to two runs and five hits over five-plus innings.

Ortiz hit a sacrifice fly in the sixth and later walked to prolong the Red Sox's eighth-inning rally. They were the last two at-bats of his major league career.

Buchholz took the loss for Boston, allowing two runs and six hits over four innings.

The outcome sets up an ALCS between the Indians and Toronto Blue Jays, who completed a three-game sweep of Texas on Sunday. Game 1 of the Indians-Blue Jays matchup is slated for Friday in Cleveland.

The Washington Nationals are now one victory away from finally earning their first-ever playoff series victory.

They own a two-games-to-one lead in their National League Division Series following an 8-3 trouncing of the Dodgers in Los Angeles. Anthony Rendon (rehn-DOHN') and Jayson Werth homered for Washington, which received 4 2/3 scoreless innings from its bullpen.

The home runs came while the Nationals were putting together a pair of four-run innings. Rendon's blast capped a third-inning rally that erased the Dodgers' 1-0 lead. Werth went deep in the ninth before Ryan Zimmerman laced a two-run double to pad the Nats' lead.

Dodgers shortstop Corey Seager drove in a first-inning run for the third straight game, hitting an RBI double after homering in each of the first two games. Carlos Ruiz added a two-run blast to get Los Angeles within 4-3 before the Nationals took control of the game and the series.

Sammy Solis (soh-LEES') worked 1 2/3 innings of relief to get the win. Losing pitcher Kenta Maeda (mah-AY'-duh) was pulled after three innings, charged with four runs and five hits.

Game 4 is Tuesday in Los Angeles.
